JOHN L. BLAOKSTOCK, OF STEPHENVILLE, TEXAS.

CHURN.

SPECIFICATION forming part of Letters Patent No. 254,909, dated March14, 1882. Application filed December 9,1881. (No model.)

To all whom it may concern:

Be it known that 1, JOHN L. BLAOKS'IOCK, of Stephenville, in the countyof Erath and State of Texas, have invented a new and ImprovedChurn-Motor, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a cheap, durable, andeasily-operated motor for dash-churns, and one the length of stroke ofwhich can be varied to suit the size of the churn and the quantity ofcream to bechurued.

My invention consists of a dash-lever, connecting-rod, crank and pulleyshaft, and large drive-wheel, the dash lever being made adj ustable asto its length of stroke.

Reference is to be had to the accompanying drawingsJ'orming part of thisspecification, in which similar letters of reference indicatecorresponding parts in both figures.

Figure l is, a sectional elevation of my invention. Fig. 2 is a planview of the same.

The frame of the motor is composed of the legs E, side and end bars, Fand G, cross-piece H, guide-arms H, and the short vertical board I,which is formed with the series of holes j, as shown.

B is the drive-wheel, placed upon the shaft 0, which is turned by thehand-crank 1, and A is the crank-shaft, provided with the pulley I),over which the belt J from the drive-wheel passes. This crank-shaft isconnected to the dash-lever K by means of the connecting-rod L. The rearend of the dash-lever is lormcd with the series of perforations a. bymeans of which it is adjustably fulcrumed to the vertical board I by thepin (Shown in Fig. 2.)

The outer end of this dash-lever is formed with the series of holes orperforations I), by

means of which it is adjustably attached to the upper end of the dasherN of the churn M, as shown; and the center of the said dash-lever isformed with the series oflholes c, by means of which it is adjustablyattached to the connecting-rod, which is also formed at its upper endwith a series of holes, d, so that,

the connection can be changed to suit the length of stroke to which thelever may be adjusted. By this means it will be perceived that the motormay be adjusted to exactly suit the different sizes of churns, and alsoto suit the quantity of cream in the churn. Besides, the motor is cheap,easily made, and effective in its work, and occupies small space whennot in use.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1 In a churn motor, the dash -lever K, formedwith the series of holes a, b, and c, in combination with the verticalboard I, formed with the series of holes j, and the connectingrod L,formed with the series of holes (I, substantially as and for thepurposes set forth.

2. In a churn-motor, the combination, with the rectangular frame E F G,the cross-bar H, thedrive-whecl B, and the crank-shaft A, provided withthe pulley l), of the vertical board I, provided with the series ofholesj, the dashlcvcr K, provided with the series of holes a b o, theconnecting-ml L, provided with the series of holes (I, and theguide-armsH,substantia-lly as and for the purpose set forth.-
